IMPROVEM ENT IN CLOI'HES-WRINGERS.

Specification forming party of Letters Patent No. 35,91 l, dated July l5, 1862.

which the upper roll of a clothes wringer or presser is forced down upon the lower roll more conveniently and cheaply than has been hitherto practiced, and by which the upper roll is made self-adjustable to permit a greater opening between the rolls at one end than at the other.

The drawing is a front view of a Wringer embodying my invention, a portion of one of the sides or posts, a, being removed to shoeT parts inclosed therein. The posts ofthe wringer are united or are framed together by the cross-girts b, and the rolls c and d are so arranged as to be capable of rotation in bearings in the post. The lower roll, d, can have only a rotary movement in its bearings; but the bearings for the upper roll, c, being slotted, permit vertical as well as rotary movement to c. Holes are bored in the posts from the upper ends thereof into the slotted bearings of roll c, so that pins e, inserted in said holes, rest or bear against or upon the shaft of roll c, within its bea-rings, and projectbeyond the tops of posts a. A Wooden spring, f, is so arranged over pins e as to rest thereupon, and the flat link h, which is hinged to the upper girt, b, and to the lcam-lever g, passes through the spring f and keeps it from being materially displaced. The cam-lever is of such form that its movement to depress the spring f constantly increases from the l position in which it is shown in the drawing till its lever is made to .assume a horizontal position in the opposite direction. The introduction of clothes, it will be seen, tends to separate the rolls by bending the spring f under the cam-lever g, and by turning the cam-lever g, it will be seen that the spring f is made to resist more powerfully the separation of the rolls. It will also be seen that when more thickness of clothes is introduced between the rolls at one end than at the other, a self-adaptation of the rolls to suit the circumstances is found by the greater deiiec tion of the spring f at one end than atthe other.

rIhe cam-lever g can be set in any desired position, and should be so set as to bring a greater stress upon the spring when passing thin pieces through the machine than when passing thick ones through. The rolls shown are formed lby surrounding the shafts with wooden cylinders, which are kept, by pins, from turning on the iron shafts, and the cylinders x are covered-with a layer of felting cemented thereunto, y v

The wringer is secured to the tub by bent
